AI summary of 5 reviews · as of May 2026
A well-built, attractive smartwatch with excellent battery life and fluid software that stumbles badly on heart-rate accuracy during exercise.
Where reviewers disagree: One reviewer found heart-rate tracking acceptable for half of indoor cycling sessions while another called it among the worst tested across sixty-four devices; Some reviewers praised the nylon strap design while one disliked the grey-red colour mix calling it a miss; Blood oxygen readings were praised as improved and accurate by two reviewers but remain unverified against scientific benchmarks
Reviewers splitWhat they praise
- Battery life extends to fourteen days in normal use, far outlasting Samsung and Apple competitors
- AMOLED display is bright, sharp, and readable outdoors with good contrast and vivid colours
- Aluminium build feels premium yet remains light at thirty-four grams with a comfortable, skinny profile
- ZeppOS 2.0 interface is smooth and responsive with minimal lag or stutter when navigating menus
- Five atmospheres water resistance and durable construction with no visible scratches after weeks of use
What they knock
- Heart-rate tracking is unreliable during workouts, often detecting half the actual rate or missing peaks entirely
- Notifications arrive late frequently, repeating the same flaw from previous generations
- App ecosystem remains limited compared to Wear OS, with no Google Maps or complex navigation apps
- Heart-rate accuracy appears highly sensitive to exact wrist position, producing hit-or-miss results
In their own words
“if you fancy yourself pretty much all of the features that you'd get in a Samsung or an apple Smartwatch but with the added bonus of superior battery life”
— Tech Spurt
“the touch response is very good and there is no lag in the menu. And I didn't see even a minor stutter or lag while going through the pages.”
— Gadget Gig
“their heart rate tracking and sleep tracking have been amongst the worst out there”

What owners single out
Buyers' weakest aspect—heart-rate tracking—directly overlaps video reviewers' finding that it's unreliable during workouts and highly sensitive to wrist position.
In their words
“I bought the GTR 4 because I was really frustrated by the poor GPS tracking on the FitBit Charge 6. Admittedly, this is a much larger device. But for around the same price, it has so many features and the GPS Dual-band positioning is both reliable and accurate. I've found that it is also easy and intuitive to use. In my eyes the GTR 4 is also much better looking as an all-day wrist-watch. It is a ”

“Great watch, heart rate is a little off when exercising. My big issue is the crown stopped working after about a year and 4 months. It won't pop back out after pushing in and it makes the watch difficult / impossible to use. I want to buy a Balance, but I am worried that the same thing will happen to that since the design is very much the same. Good but not sure if I just got a lemon or if they al”
